[PATCH v2 0/2] Add support for power budget

[Kory Maincent]

In preparation for future support of PSE budget evaluation strategy and
power management, we need the power budget value of the power supply.

This addition allows the regulator to track the available power
budget, which will be essential for prioritizing ports when
making power allocation decisions.
